lTo all whom it may concern: l

-Beit known that I, JOHN JOSEPH Cooienn, a subjectl of the King of Great Britain, and resident of 120 Queen Victoria street, London, E.' C., England, have invented certain new and useful Improvements in Type- Iriting Machines, of which the following is a specification. l

This invention .relates to typewriting machines adapted to enable a carbon or like duplicate copy of the entries comprised 4in av series of invoices (.or similar documents) to be` taken on acontinuous stripof paper con- Y currently with the typing of the original entries upon'vthe individual invoice-forms (or similar sheets of paper) themselves The present invention is designed to pro'- /Vide means for automatically feeding forf.

1 4ward the sheets or strips of paper for the lreception ofthe original and duplicate writings at different velocities, so as to obtain a different width of spacing betweenI the lines in the original and duplicate respectively. Tothis end the strips or' 'sheets of paper which respectively bear" the original and duplicatefaie fed forward by frictional contactivitli independent. lengthsor sections of lthe platen, these sections being rotated concurrently With one another but at different peripheral velocities corresponding to the different speeds of advance required in the case of the respective papers. However, while the platen is composed of a plurality ofindependent sections or lengths, its printingarea is confined to the fm'iddle section and does not extend to the end sections, so

that the sole function of the latter, therefore, is to lfeed the sheet held thereagainst, although the end portions of the middle section also eXert a feeding action. In other words, the middle section serves both as an l' impression `support or backing against Whicli'the types strike, and as a feeding means for the sheet,wiile the end sections are used for feeding purposes only, and,

hence', form ,-revogiuble feeding elements or .i Adevices which rotate separatelyfrom 'the middle section. Ilccordingly, the aforesaid middle section may be considered as the platen-body, and the end sections as eXtensions thereof, or 'as auxiliary platens, and

inthe subsequent description, as well as in certain of thel appended claims, these terms will be employed. 'For the purpose above stated, the independent lengths into which which the cylindrical platen is divided, are in driving connection with the line-space lever in the one case directly, and in the other casethrough the medium of gearing proportioned so that the speed of rotation Aof one length of the platen is greater or less than that of the, other length, so that actuation of the line-spacing mechanism will produce a; simultaneous partial rotation of thevarious' lengths into which the platen is divided, through different angular distances. Each length is furnished with its own feed rollers, and consequently the strips or sheets of paper which are held by these rollers in frictional contact with the several lengths receive motions of advance whose respective amplitudes dier in the same degree as do the angular distances through which the corresponding platen-lengths or sections themselves arerotated. In view of the fact, just stated, thatvfeed rollers are provided for themselves be considered as uniting to form a single set of revoluble feeding elements. Ingojder that the strips or sheets of paper Jsrerto receive the original and duplicate Writings respectively, may be adjusted on the platen, when necessary, relatively to or independently of one another. a friction-clutchscapable of being disconnected at will-, isI interposed in the gearing whereby rotary motion is transmitted between the platen-sections appertaining to the different papers, while the feed rollers for the lengths constituting the respective platen-sections are made capable of being thrown into and out vof action independently of one another. It being, as a rule, required that the lines in the duplicate shallV be spaced apart more widely than those of .the -original writing, the invention will, for the sake of convenience, be described with special reference to a construction for enabling the wider spacing to be giveny to the duplicate.. With such a construction', in order thatthe "iluplicatef strip of paper may be readily-1 severed'be#l i, p. linthe example illustrated,tlie.middle s I tion or pla'ten-body''ffiii is fast on the platen tween any two lines oilwriting, this strip,

on passing the printing-point, would bev made to issuev through an aperture provided with a knife-edge againstl whichthe free end portion of the strip may be torn olf after receiving 'the impression of any particular line.

trate a convenient arrangement embodying the invention, Figure 1 is a general' plan,l

view of the carriage of a typewriting machine, whereof the cylindrical platen is shown as divided into three lengths or sections. lFig. 2 is an elevation of the platen and countershaft (partly in section onthe axis of the platen.) as viewed ina direction perpendicular to the line 2'-2 of Fig. 3. Fig. 3 is an end view of the carriage, the hand-wheels shown in Figs. 1 and 2 being removed.l Fig. 4 is a vertical transverse-section on line ir-4,- of Fig. l. Fig. 5 is a cletail view, showing a tension-device for the stock-roll whence the duplicate strip is unwound. Fig. 6 is a partial end view oi' the platen, drawn to a larger scale, showing means for throwing` the feed rollers into and out ofaction as required. Fig. 7 is al part vertical transverse section on lirici-7 of, Fig. l, showing the line-spacing mechanism. Fig. 8 is a diagrammatic plan view. Fig. 9 a perspective view of the platen, illustrating the manner in which the several lengths into which the platen is divided, op-

crate upon the respective strips or sheets of paper bearingthe original and' duplicate .\;vi.^itings.l Fig. 10 is a section taken at right angles to Fig. 6, showing the eccentric shaft on which the feed rolls are mounted.'

As will be seen by reference to Figs. 8 and 9, the cylindrical platen (which in Figs. lV

and 6 is marked A) is divided intofa rela- .tively long or wide central section or body A1 and two relatively short end sections or extensions A2 and AS.

C represents the continuous strip of paper.'

which is to receive the duplicate impression,

' this strip being of a width to contact only with the central sect-ion A1 ot the platen.-

B represents a sheet (or strip) oi paper Such as an invoice form (or continuous 'series of identical invoice forms) whereon the original'writing is to be typed, this sheet ,(or strip) being so much wider .than the .section A1 as to over-lap and maintain con tact with, both of the end-scctins A2, A3 of the platen. The sheet yD of carbon paper `(Fig. 8') which is inserted as usual between the worksheet B and duplicate strip C should be wide enough to'contact with the end sections A2, A3 so as to be fed forward along with the sheet or'strip' B.

The printing area, however, is restricted to the middle section orlmdv Alffmd a nfl spindle e, while the end sections or greater speed) and the end sections A2, In the aconipanying drawings which 1llus- 5b ei'ng obtained by rotating-the platen-spindie e directly by' means'of the Aline-spacing- 5 mechanism, through a relatively .large angle,

and driving the sections A?, rcrn'the spindle ctlirough 'the 'medium of gearing whereby their angular motion is reduced be# low that 'ofthe middle section A1 in the re` bodyA1 which drives' the duplicatestrip C being caused to rotate lthrough nine units ord angular advance during. the rotation. of the end sections or extensions-A?, A3 through. only only one such unit. 'Accordingly the` yline-space pawl E,which"drives the line` space ratchet-wheel'E1 (the latter being fast [l on the platen-spindle a) is made to swing about the axis of this ratchet-wheel through an interval equal to nine teeth of the wheel i at each .actuation of the springretracted' line-space lever E2; this leven-which isulcrumed at e on the carriage F of the inachine, beingv coupled by a linlr e2' to the arm" e1 which is mounted to swing about the axis greater than usual, that arm ofthe lever E- to which the linh' e2 is connectedismade specially long. For the same-reason itis found generally convenient, 'instead ofapplying the usual stop-pawl'- to the 'saine los.

ratchet-wheel E1, to provide the platen-spinl dle a with a second ratchet -wheelll3 (Fig. V 2) for engagement by the ordinary stopv i pawl or juniper .'(not shown) whereinr .accidental overdriving'of the platen is prevented.

I Each ofthe end sections A2,'A3 of .the platen has fixed -to its outer end a ltoothed wheel G, the two 'wheels G being of equal Y diameter and gearing respectively with pinions G1 fast on a counters'haft g' which is',v journaled in bearings gll (Fig:v 2) mounted,

For thepurpose of enablingthe .f

A3 of the platen and guided around the same by pairs of feed-rollers J mounted beneath the platenas usual and provided with means whereby the rollers may be thrown ,into andout of operation at will.

i The strip C which receives the duplicate writing is held in Contact with the middle section A1 of the platen, by means of rear -and front pairs of feed-rollers K1, K2

mounted, above the level ofthe plateneaxis, in a frame comprising rear and front parallel spindles Isl, 7a2 upon each of which one v'yokes K which connect together thev muf pair of the rollers is fitted to revolve, and

litted to turn in bearings m1m2 on the carv riage F, so that, by rotating the shaft through about one-half revolution .in one direction or the other, the feed-rollers K1, K2 will be caused to bear against orrecede from the surface of the middle platen-sectionA1 as the case may be. -At one end the y shaft` L is provided with a hand-lever M wherebv it may be rotated as described, at

The support provided consists of an openwork guide in the form' of an arched or U- shaped radius-arm Q (preferably of bent lwire as indicated) which is mounted to rock about the spindle 7a2 and is yieldingly sup- --p'orted as by spring-pressure so as to tend to maintain an approximately upright position just clear of the roll ci? paper on the spool N The free end portion of the strip C, as it falls forward after passing the knife C), comes in contact with the arm Q, and travels-upward along the latter as indicated in Fig. 4:, so that at any point in its progress the end of the' strip maybe readily grasped and drawn forward, .the guide or support Q yielding to the pull. In the example illustrated, the spring p1 already ymentioned .serves to maintain the guide Q in normal position, for which purpose the front end of the spring is attached' to ay short arm p projecting from one of a guide i's mounted to rock'aboutthe spindle The arm' p normally extends in substantial alinement with the direction in which the spring p1 exerts its power, so that, while capable of easy displacement when the 'guide 4Q is depressed during the operation of' tearing ofi' the end portion of the strip.
